Unfaced Metal Building Insulation (MBI) is a resilient, flexible fiberglass blanket. Unfaced MBI is used to provide additional layers of insulation in systems to achieve higher R-values as well as to fill the purlin cavity of liner systems.
Bay Insulation offers both NAIMA 202-96® unfaced MBI as well as Metal Building Filler Blanket, depending on the needs of our customers. For more information on Filler Blanket, see Bay Insulation Systems’ Stance on Filler Blanket.
